Shifting bird and reptile distributions
April 8, 2014 12:23 PM - Robin Blackstone, ENN
With climate change come several dramatic shifts in species distribution within the United States. The U.S. Geological Survey in concert with the University of New Mexico and Northern Arizona University have recently projected distribution losses for nearly half of the 5 examined reptile species including the locally famed chuckwalla. Breeding bird ranges, however exhibited broader expansions and contractions within their breeding habitats.
Fences May Cause 'Ecological Meltdown' of Wildlife
April 8, 2014 08:04 AM - Wildlife Conservation Society
Wildlife fences are constructed for a variety of reasons including to prevent the spread of diseases, protect wildlife from poachers, and to help manage small populations of threatened species. Human—wildlife conflict is another common reason for building fences: Wildlife can damage valuable livestock, crops, or infrastructure, some species carry diseases of agricultural concern, and a few threaten human lives. But in a paper in the journal Science, published April 4th, WCS and ZSL scientists review the 'pros and cons' of large scale fencing and argue that fencing should often be a last resort.
Desert absorption helps curtail CO2 levels
April 7, 2014 09:55 AM - Eric Sorensen, Washington State University News
Researchers led by a Washington State University biologist have found that arid areas, among the biggest ecosystems on the planet, take up an unexpectedly large amount of carbon as levels of carbon dioxide increase in the atmosphere. The findings give scientists a better handle on the earth's carbon budget — how much carbon remains in the atmosphere as CO2, contributing to global warming, and how much gets stored in the land or ocean in other carbon-containing forms.
Badger Culls in England Will Not Expand
April 6, 2014 09:32 AM - Judy Molland, Care2
This is great news for most of the badger population of England. Plans to roll out the controversial badger cull pilots nationwide across England have been dropped by the Environment Secretary, Owen Paterson, after an independent report found the shoots were not effective or humane. The pilot programs were run in Gloucestershire and Somerset in an effort to stop the spread of Bovine Tuberculosis among cattle, and the environment department's original plan was to announce up to 10 new cull areas each year.
Unearthing of large tusk in Arabian Desert suggests once greener pastures
April 4, 2014 09:49 AM - ENN Staff
Working in conjunction with the Saudi Commission for Tourism and Antiquities, researchers from the University of Oxford have discovered two pieces of a tusk that when combined measure six feet in length. The researchers believe it is from a Palaeoloxodon or a "straight tusked elephant". An elephant's carpal bone was recovered in a separate study done by a Swiss team in the Nefud Desert just five meters away. The sand layer dates back to approximately 325,000 years and the elephant is believed to be of the same age.
Wild Bees Improve Farm Revenues by Boosting Crop Yields

Investing in habitat that attracts and supports wild bees in farms is not only an effective approach to helping enhance crop pollination, but it can also pay for itself in four years or less, according to Michigan State University research. The paper, published in the current issue of the Journal of Applied Ecology, gives farmers of pollination-dependent crops tangible results to convert marginal acreage to fields of wildflowers, said Rufus Isaacs, MSU entomologist and co-author of the paper.

Climate change has been a constant reality for many Filipinos, with impacts ranging from extreme weather events to periodic droughts and food scarcity. The most affected populations are coastal residents and rural communities that lack proper disaster preparedness.
H&M, Zara commit to cutting rainforest destruction out of clothing production
April 3, 2014 11:18 AM - Rhett Butler, MONGABAY.COM
H&M and Zara/Inditex, two of the world's largest clothing companies, today pledged to eliminate old-growth forest destruction from their products. The commitment lends support to a new front on efforts to cut deforestation from supply chains of global brands.
American's energy usage jumps in 2013
April 2, 2014 01:08 PM - ENN Staff
Despite many individual efforts to decrease energy usage for 2013 increased by 2.3 Quadrillion thermal units over the previous year. These statistics have been monitored and presented by the Lawrence Livermore National Laboratory (LLNL) in the most recent energy flow charts measuring renewable, fossil and even nuclear energy.
Can Technology End Overfishing?
April 2, 2014 07:57 AM - Alexis Petru, Triple Pundit
Back in 2002, Thomas Kraft, managing director of Norpac Fisheries Export, came up with the idea to electronically track each fish the company captures and sells. Soon after Norpac's electronic monitoring system was up and running two years later, Kraft realized that the technology was not only an effective management tool, but it could also help the company trace fish through the supply chain and guarantee its products were not caught using illegal, unreported and unregulated (IUU) fishing practices.
